Research Overview
Selank is studied in neuroscience research using animal models of stress, including its interaction with cytokine signalling and GABAergic systems.
Researchers have also compared its effects with the related peptide Semax using functional-connectivity approaches.

Selank: Research Background
Selank was developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. Its core, Thr-Lys-Pro-Arg, is tuftsin, a natural fragment of the immunoglobulin G heavy chain; a Pro-Gly-Pro tail was added for stability.
Animal research has examined Selank’s effects on gene expression related to GABAergic signalling, on cytokine expression including IL-6, and on enzymes that degrade enkephalins.
Because it shares its Pro-Gly-Pro tail with Semax, the two peptides are often studied side by side, including in functional-connectivity research.
What the Selank COA Confirms
OxygenLab products are tested by independent third-party laboratories. HPLC reports purity as the main peak’s share of total peak area, and mass spectrometry confirms identity against the expected molecular weight of 751.9 g/mol. Published certificates are on our COA page, and others are available on request; match the lot number on your vial to the report before use in an experiment.

More Questions About Selank
What is tuftsin?
A four-residue peptide (Thr-Lys-Pro-Arg) cleaved from the immunoglobulin G heavy chain. Selank is built on this sequence.
How many residues does Selank have?
Seven: Thr-Lys-Pro-Arg-Pro-Gly-Pro.
Storage and Handling
- Store lyophilized powder at -20°C for long-term storage, protected from light and moisture.
- Short-term storage at 2–8°C is acceptable for unopened vials.
- Allow the vial to reach room temperature before opening to limit moisture uptake.
- Record batch and lot numbers for every preparation.
